What's up with my brain?

I have a brain coral that I got from a friend. It has been nipped at by a flame back angel for the past couple of weeks. Within 3 hours of putting it in my tank it seems to be plumping up. I can see some of the plates where it has been receding. Is there any hope for this to survive? Sorry if the pic is blurr...iphone.

 

Feed him every night and hope that helps, along with good water and enough light.

 

was the angel in your tank or your friends??? if its in the same tank now i would say doubtfull, not impossible. but if there is nothing to pick at it now and parameters are ok i would think it should make a recovery.

 

We moved the brain to my tank without the angel, so it won't be provoked anymore.

 

I've heard they're pretty resilient when given a proper environment. If that's true, I would just make sure it gets fed a decent amount so it grows back the tissue faster, and doesn't get picked on or have any algae grow on the exposed skeleton.
